Description Usage Arguments Value Author(s) References See Also
These functions compute the values a_1^* and b_n^*, the value of the estimate of the upper function at x_1 and the value of the lower estimated function at x_n in the two ordered antitonic regression functions problem. These values can be computed via explicit formulas, unlike the values at x \in {x_2, …, x_{n-1}}, which are received via a projected subgradient algorithm. However, b_n^* enters this algorithm as an auxiliary quantity.

Values of a_1^* and b_n^* are returned.
